Submergence detection power-window apparatus

Abstract

A submergence detection power-window apparatus is provided with driving motors for moving electric-power driven opening units to opened and closed states, manual switches for manually opening/closing the electric-power driven opening units, control units for driving the motors into rotation in accordance with operations carried out on the manual switches, a submergence detector for detecting submergence of a car body and generating a submergence detection signal and a fastened/loosened seat-belt detector for detecting fastened/loosened states of a seat belt and generating a loosened-seat-belt detection signal in a loosened state of the seat belt wherein the control units drive the motors into rotation in directions to open the electric-power driven opening units when the manual switches are operated to open the electric-power driven opening units provided that a submergence detection signal is received from the submergence detector and a loosened-seat-belt detection signal is received from the fastened/loosened seat-belt detector.

What is claimed is:  
     
       1. A submergence detection power-window apparatus, comprising: 
       a motor to drive opening and closing operations of an electrical-power driven opening unit;  
       a manual switch to open and close the electrical-power driven opening unit;  
       a control unit to drive the motor in response to an operation of the manual switch to open and close the electrical-power driven opening unit;  
       a submergence detector to detect submergence of a car body and generate a submergence detection signal indicating detected submergence; and  
       a fastened/loosened-seat-belt detector to detect a fastened state and a loosened state of a seat belt and generate a loosened-seat-belt detection signal indicating a loosened state of the seat belt,  
       wherein the control unit drives the motor in a direction to open the electric-power driven opening unit when an opening direction switch of the manual switch to open and close the electrical-driven opening unit upon reception of the submetgence detection signal from the submergence detector and the loosened-seat-belt detection signal from the fastened/loosened-seat-belt detector.  
     
     
       2. A submergence detection power-window apparatus according to claim  1 , wherein the fastened/loosened-seat-belt detector generates a loosened-seat-belt detection signal when a fastening unit of a seat-belt buckle is loosened. 
     
     
       3. A submergence detection power-window apparatus according to claim  2 , wherein the fastened/loosened-seat-belt detector has a fastened/loosened-seat-belt detection sensor provided on a seat-belt winding unit. 
     
     
       4. A submergence detection power-window apparatus according to claim  1 , wherein the fastened/loosened-seat-belt detector generates a loosened-seat-belt detection signal when the seat belt is disengaged. 
     
     
       5. A submergence detection power-window apparatus according to claim  1 , wherein the electric-power driven opening unit is a window on a driver-seat side. 
     
     
       6. A submergence detection power-window apparatus according to claim  1 , wherein the electric-power driven opening unit is a window on a driver-seat side and an electric-power driven sunroof.
